Recognizing and Unplanned Release

Use caution in the event of a suspected pipeline leak or in the event of any of the following suspicious conditions:

Sight:

Some gaseous and most liquid leaks or releases may be visually detectable. A dense white cloud or fog originating near a pipeline marker, vent or above-ground equipment may be the result of a leak. Extra caution should be used to avoid ignition as such fumes and mists are likely flammable.

Dust blowing from a hole in the ground

Dead or discolored vegetation in an otherwise green area

Continuous bubbling in wet or flooded areas

Flames, if a release has ignited

Large ice ball formation on above-ground piping

Sound:

You cannot always see that there is a pipeline leak. Dow transports a variety of products, some of which may not be detectable by sight should a leak occur. However, hearing a hissing or blowing sound may identify a release depending on the size of the release

Smell:

Products escaping from a pipeline may sometimes be detected by a gas or "smelly oil" odor

The vast majority of products Dow transports are hydrocarbon based products which means that they will ignite and burn if released and exposed to an ignition source.

It is always best to call Dow Product Control if you have any reason to suspect a leak from one of Dow’s pipelines. Dow’s 24 hour emergency numbers are as follows:
